50mm lens shootout

Seven 50mm prime lenses for Nikon F-mount compared

Cary Jordan compares seven 50mm lenses for Nikon F-mount including several Nikkor lenses, Sigma, and Carl Zeiss.  Full results at the link below.

Overall, your best bet is the Nikon AF-S Nikkor 50mm f/1.8G Lens.  You can buy the f/1.4 version at substantially more cost but most people don't need the extra speed.

Internet Explorer drops below 50% market share

browser market share

Interesting browser market share stats at Ars Technica.  Combined market share for IE is below 50%, Safari dominates mobile browsing.  Personally, I have switched to Chrome from Firefox and don't see any reason to switch back.  I haven't used IE in years other than to view pages that require it.

Giant Negative

A Six-Foot-Long Camera That Shoots Enormous Photos

For some people film is superior to digital, for others film is a joke and medium format is the only way to go. for one guy, no existing camera was good enough so he decided to build this monster that produces negatives 3 feet long!

iPhone Test 1

iPhone 4S vs Canon P&S vs Nikon D90

An image shootout between the iPhone 4S, a digital point and shoot (Canon SD870 IS), and a digital SLR (Nikon D90). I have tried to match focal length as best I can.  On the Canon I zoomed in slightly to try and get the same field of view.  On the Nikon I used a 14-24 lens at 24mm.

iPhone Camera

  • Sensor: 8 megapixel CMOS sensor (1/3.2")
  • Focal length: 4.28mm
  • Aperture: f/2.4
  • Image dimensions: 3264 x 2448

Interesting technology, remains to be seen how well it works in the hands of consumers. May become the new standard for digital sensors if they can increase the resolution.

Lytro introduces world's first light field camera: f/2 lens, $399, ships early 2012

A quick review of the iPhone 4S

Hardware

Signal strength for cellular and WiFi seems stronger. When choosing from Wifi networks, I get more options than I did with the iPhone 4 in the same locations which suggests it's picking up things further away. Also, I can pick up my company WiFi signal further away. Well done Apple, this is a change everyone will appreciate.

The new dual-core A5 processor (800MHz) is an improvement over the iPhone 4 and this phone feels faster overall, especially when using the photo app. Things render just a bit faster.

Screen is the same, but still excellent if not the best on the market.

Camera is improved, it's faster and 8MP. I haven't used it enough to comment on the performace though. I do love the fact that iOS 5 allows me to launch the camera from the lock screen, handy if you need to pull out your phone for a quick snap.

Software

Notification center is a 1000% improvement over the previous system. It's now not annoying and useful, something Apple should have done years ago.

Still no week view in the calendar app, lame.

Addition of iCloud is nice, a backup away from the computer is certainly the way of the future.

Siri, the voice assistant. I'm not sold on it yet, it worked well for some things but not others. It can't find restaurants in Canada, nor can it give directions making it less useful. It does have location and geofence capability, so for example it knows where you work and if you are currently there. I can then tell Siri to "remind me to call my wife when I leave work" and it will create a reminder that triggers when I leave the office. I think I need to live with it for a while, but it could be an interesting feature.

Overall, a good upgrade to the iPhone 4.


Canon 1D X top

Canon Unveils the 1D X

Wow, Canon just took the wraps off a new DSLR.   It's a blend of their previous two high end models, mixing high speed and a full frame sensor.  14fps, 18-megapixel full frame shooter, sounds like a winner if you have the cash ($6800 when it ships in March 2012).

JPEGmini - Your Photos on a Diet!

Great service that compresses your jpeg images for the web.  All of the images I have uploaded to the site so far have been compressed with JPEGmini.  You can use higher compression when saving in Photoshop or other image tools, but JPEGmini maintains quality a lot better.  I'm hoping they have an export plugin for Lightroom and Photoshop soon.

Testing "WP Retina 2X" Plugin For Wordpress

Now that Wordpress 4.4 is out (and used on this site as of December 8, 2015) I wanted to test the Retina 2X plugin for Wordpress to see how it works and if it makes a difference on my 4K monitor and iPhone.  I exported two images from Lightroom, one is 1024 pixels wide, the other 3840 pixels wide (4K).

1024 pixels version below.  The blog displays images here at 818 pixels wide, and if you click you get the large version. 2015-04-17-Arizona - 1024 Wide

 

The 3840 pixel version.  The theory is that high resolution displays should show a higher quality version than the one above (which is limited by the file size).
